摘要
目的运用微波技术从红景天根、茎、叶中提取有效成分总黄酮、多糖,并测定其含量。方法分光光度法。结果测得红景天根、茎、叶中总黄酮含量分别为4.62%、1.36%、2.82%;多糖含量分别为9.12%、3·57%、3·01%。结论首次运用微波技术辅助测定红景天中总黄酮和多糖的含量,反应速度加快,收率提高。
OBJECTIVE The extraction and content determination of total flavone and polysaccharide of Rhodiola rosea L.METHODS Microwave Technique Applied in total flavone and polysaccharide of Rhodiola rosea L.were obtained for extraction in content determination.RESULTS The taital flavone content in different locus of Rhodiola rosea L.are 4.62%、1.36%、2.82%,The polysaccharide content in different locus of Rhodiola rosea L.are 9.12%、3.57%、3.01%.CONCLUSION Microwave Technique Applied in The total flavone and polysaccharide of Rhodiola rosea L.has been obtained for the first time.
